Er, Chichi, Mary Magdalene wasn't stoned to death as a prostitute or an adulteress. She was alive and well at Jesus' resurrection. As a matter of fact, she is never mentioned as an immoral woman, only as a woman in need of Christ's healing in scripture. The woman whom you refer to is an unnamed woman "caught in adultery." It was not Mary Magdalene and this unnamed woman was not stoned either presumably because of Jesus' intervention and his words to the crowd, "He who is without sin, cast the first stone."
